ERECTING CRANE AND GIN POLE.

Application filed January 15, 1923. Serial No. 612,817.

T0 all whom 'it may concer/n.'

Be it known that I, FoKKo BRANDT, a citizen of the United States, andresident of Kansas City, county l'of Jackson, State of Missouri, haveinvented a certain new and useful Improvement in Erecting Cranes and GinPoles, of which the following is a complete specication. y

This invention relates to erecting cranes and gin poles for derricks,and has for its object to produce -an apparatus adapted for` attachmentto the frame of the derrick at different heights as the height of thederrick increases, for the purpose of raising or lowering parts,particularly heavy parts, for incorporation -in the derrick, or for usein conjunction therewith for handling well casing, pumping apparatus andthe like.

More specifically, the object is to produce lifting apparatus forenabling parts to be etiiciently raised or lowered within the derrickand thereby minimize the chance of injury to workmen or others, fromfalling parts or the like, and utilize the derrick structure itself-as asupport for liftingand lowering parts without imposing lateral ortwisting strains on the structure.

A still further object is to produce apparatus which can be easily andquickly secured in or removed from Operative position at any elevation,and which possesses maximum strength combined with light weight andeconomical construction.

With these objects in view, the invention consists in certain novel anduseful features of construction and combinations of parts as hereinafterdescribed and claimed; and in order that it may be fully understoodreference -is to be had to the accompanying drawings, in which:-

Figure l is a side elevation of the lower part of a derrick in course oferection and showing a crane in its lowest operative position thereon;

Figure 2 is a side elevation of the top of the derrick and showing thegin pole thereto in operative` position;

Figure 3 is a top plan view of the gin pole with the derrick inhorizontal section adjacent the plane of the lower ends of the legs ofthe gin pole;

Figure 4 is an enlarged vertical section through the adjacent end of onepair of the leg sections of the derrick and the sleeve connecting suchsections, the figure also showing the relation between said sleeve andthe lower end of a crane;

Figure 5 is a section on theline V--V of Figure 4;

Figure Gis a perspective view of a pilot pin employed at the adjacentends of superposed leg sections of the derrick;

Figure 7 isa fragmentary side elevation of the gin pole construction;

Figure 8 is a similar view with a part in central verticalsection;

Figure 9 is a vertical section of the sameconstruction taken at rightangles to the section of Figure 8; and

Figure 10 is a .detail perspective view of part of the crane and pinpole construction.

ln the said drawings, l indicates the base frame of a derrick or thelike, resting on concrete piers 2, the corner posts 3 of the derrickbeing composed of sections connected together by coupling sleeves 4. Thesleeves at corresponding heights,`are connected by horizontal tie bars5, and'sleeves of adjacent levels with one or more exceptions noted, areconnected by crossedbraces 6. At a suitable height, one tier or panel ofthe derrick, at one side, as shown, has adjacent tie bars 5 connectedintermediate their length by spaced uprights 7, to leave a space orpassage for the operation lofa walking beam (not shown) if desired, andthe framework at opposite sides of saiduprights is .stiened by crossedbraces 8. The

special construction of the framework, how

ever, is important in this connection only in Irelation to the sectionalconstruction of the corner posts and in the special type of couplingsleeves for the sections of said posts, as 'l the constructionalfeatures mentioned are important with respect to the crane and gin pole.-Reference is also made at this point tothe crown block assemblyf9, atthe top of the de rrick, though the particular construction thereof isof no importance as regards this invention, except in `the fact -that itis composed of parts preferably assembled together after individualelevation to operative position and disconnected so that such parts orelements may be in- 4 dividually lowered to the ground.

ends of the post sections the coupling is diametrically enlarged as at10, (see Figure 4) and from the lower end of such enlargement is splitas at 11 to its upper end. At opposite vsides of thesplit are lugs 12 tobe brought together to clamp the sleeve upon the upper post section, bya clamping bolt 13. Centrally of the said enlargement, the couplingsleeve is provided at diametrically opposite points withinwardly-projecting segmental lugs14 (see Figure 5) abutted at its underand upper sides by the ends of the underlying and overlying postsections, and at its lower end the coupling sleeve is provided with aperforated lug 15. To strengthen the post section connections butprimarily for guarding against relative turning movement of saidsections, a pilot pin is provided, composed of an upper portion 16secured immovably in the upper post section, a reducedflower portion 17.fitting in the underlying post section and a neck portion 18 from whichprojects opposite segmental lugs 19 fitting in the spaces between lugs14 and cooperating with the latter' in carrying the load and preventingrelative turning movements of the post sections, the pins also havingtongues 2O projecting through the slits 11.to serve as guides inreadily'interposing the lugs 19 between the lugs 14 and thereby insurelongitudinal alinement of all of the perforated lugs 15 of j loweringrope 26.

the respective corner posts of the derrick to provide for the readysupport of a crane or gin pole element, as for the proper supportthereof,two of the sleeve-lugs 15 are employed, as will be noted byreference to Figuresl and 2.

For quickly and easily raising or lowering post sections, braces, etc.as the erection or dismantling of the der rick progresses, one or morecranes will be found convenient, and such cranes when coupled in pairsto constitute what is known as a gin pole, serve for raising andlowering material and the vlike within the derrick.

The type of crane employed, comprises a pipe 21 provided with a pair ofarms 22 having depending pins 23 for pivotally engaging a pair of lugs15 of adjacent sleeve couplings, said pipe having an.oppositelyprojecting arm 24 at its' upper end for the support of asheave 25 and a lifting and As in the erection and dismantling of thederrick, the usefulness of the crane at any 'particularlevel ceases. itis shifted to a higher or lower level and engaged with a diderent pairof lugs 15, this adjustment being repeated until. all parts have beenraised or lowered.

TWhen the derrick is completed and it is desired to provide for liftingbeams for the crown. block or other heavy parts. a pair of cranes aresecured as explained, on diagonally-opposite corner posts, and connectedat their upper ends by a bar 27 (seeFigu'res 2 and 3). To make suchconnection secure and provide a stable and self-adjustable connection ateach end of the bar, the arms 2.4 at the top of the cranes, are providedwith diametrically slotted concave heads 28, and brackets 29 secured tothe bar, have stems 30 extending through the slotted heads 28 and intothe cranes, and downwardly-facing convex shoulders 3l engaging saidconcave heads, the arrangement being such that the bar is firmlysupported should any slight inequality' exist in the angular positionsof the cranes from any cause. To facilitate the ascent and descent ofthe derrick, one of the corner posts may be equipped with steps 32,clamped or otherwise firmly secured in place.

From the above description it will be apparent .that I lhave produced astructure embodying the features of advantage set forth in the statementof the objects of the invention and other desirable features, and it isto be understood that the invention is susceptible of modification invarious particulars within the principle of construction and mode ofeperation involved without departure from the scope of the appendedclaims. I clai'mz.
